Multiple profile #GrapheneOS on my phone, with my main profile being de-Googled and mainly FOSS.

Privacy-respecting email service - #ProtonMail or #Tutanota would work.

Privacy-respecting search engine - #DuckDuckGo, #Qwant... many to choose from.

I'm progressively deleting social networks, apps, and useless accounts as well.

Sadly, real life forces me to depend on privacy unfriendly apps such as #WhatsApp, or regular banks. But, I do what I can with what I have.
